Jim Harris 82c3c30f44 trace: remove alias concept
This was added a long time back for tracking an rte_mbuf
whose buffer was a different rte_mbuf - all related to
a userspace TCP stack that is no longer in development.
The concept isn't useful now, so remove it to reduce
the complexity of the tracing code.
